Voters in Montana, Nevada, Arizona, Colorado, Missouri and Ohio all appear to have approved an increase in their states' minimum wage, The Washington Post reports. All six, like Oregon's, will carry annual cost-of-living adjustments. Nevada's hike applies only to workers without on-the-job health benefits. HR.BLR.com has a detailed rundown and links to each ballot measure. The highest wage approved last night was $6.85 an hour in Ohio and Colorado. That's still lower than Oregon's current minimum of $7.50 (It rises to $7.80 on Jan. 1).

Those hikes might soon become moot, however. Democrats, who seized control of the House in last night's elections and might also gain control of the Senate, want to raise the federal minimum wage from $5.15 to $7.25 an hour.
